  • Patent number: 4490180
    Abstract: A method for electrohydroblasting of castings in a liquid medium with a view to removing core and molding sand, according to which castings are subjected to a series of electrohydraulic shocks and at the same time set in reciprocating motion. The reciprocating frequency of the castings and the length of their stroke are sufficient to produce a flow of liquid in the internal channels of the castings and thus remove core and molding sand therefrom. The method is carried out with the aid of an apparatus which comprises a casting-reciprocating mechanism interacting with an electrode-positioning mechanism so that the movement of the castings is synchronized with that of the electrode.

  • Patent number: 4198995
    Abstract: An apparatus for electrohydroblasting of castings comprises a base, a bath, a mechanism for feeding castings into the bath, having a movable platform mounted in vertical guides, and a loading device. The loading device comprises horizontal guides and a means for conveying castings along the horizontal guides. The horizontal guides have a section disposed above the bath and sections mounted on the base. In accordance with the invention, the section of the horizontal guides, disposed above the bath, is mounted on the movable platform of the mechanism for feeding castings into the bath.
